802.1Q VLAN Setup
Advantech B+B SmartWorx managed switches also support IEEE 802.1q VLAN. Implemented 802.1q
VLANs can extend over multiple switches. Switches can be from different manufactures as long as they
support 802.1q
A typical 802.1Q VLAN network and the web server configuration page can be found below. Note the
difference between VLAN ID (frames that are tagged) and PVID (frame that are untagged).
The configuration page displays the default PVID value for 802.1Q VLAN. Each port can be configured to
filter (remove) the 802.1Q tag or pass the 802.1Q tag to the connected device.
Tag Filter Setting:
• Untagged - 802.1Q tag removed
• Tagged - 802.1Q tag passed on. If the tag is not present, an 802.1Q tag will be added.
The illustration below shows the Tag Filter configured for both untagged and tagged port settings. Most
PCs would be connected to a switch port that was configured for Un-tag. The two ports connecting the
switches together are uplink ports and should be setup as Tag ports.
